The 1.5 terabyte claim has not been confirmed, though Variety notes that an HBO security contractor revealed in a filing that the hackers obtained “thousands of internal documents.” A contrasting report from The Washington Post also says U.S. intelligence officials believe the HBO hack is actually smaller than the Sony data breach, so it remains unclear when an official assessment of the leaks will take place.

Still no motive has been obtained for the hack, though information was said to be specifically targeted, as opposed to the recent Orange Is the New Black theft. We'll see if Sunday provides any context to what may be an ongoing headache for HBO.
